3. Selecting Installation Site
NOTE:
„
Do not throw away any of the accessories until installation is complete.
„
Hold the unit by the hunger brackets (4) when opening the box and moving it, and do not lift it
holding on to any other part especially the refrigerant piping.
„
If you think the humidity inside the ceiling might exceed 86°F and RH80%, reinforce the
insulation on the inter-unit piping.
„
Use glass wool or polyethylene foam as insulation so that it is no thinner than 3/8’’ and fits
inside the ceiling opening.
(1) Select an installation site where the following conditions are satisfied and that meets with your
customer’s approval.
• Where is resistible against weight of BS unit.
• Where sufficient clearance for maintenance and service can be ensured.
• Where the total piping length involving indoor unit and outdoor unit is below the allowable
piping length. (See installation manual attached to outdoor unit.)
• Locations where there is no possibility of flammable gas leaking.
• Locations where the wall is not significantly tilted.
• Locations where an inspection hole (see figure below) can be installed.

(Sight opening must be of above size and provided in front of electric parts box.)
NOTE: 1. Leave 4’’ of service space below the electric parts box.
If this is not possible, open a service hole in the location
indicated in the figure below.
2. Make sure the power, branch, and remote control wiring of the
indoor, outdoor, and BS units are at least 40’’ away from radios
and televisions. This is to prevent interference with picture and
sound reception. (Interference may occur even at 40’’ away
depending on the reception quality.)
(2) Use suspension bolts for installation. Check if the location for the installation is strong enough to
support the weight of the unit, reinforce it if necessary, and install using suspention bolts.
